GEORGE H. PERKINS, OF PHILADELPHIA, PENNSYLVANIA.

NAILING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,331, dated April 19, 1881.

Application filed June 2}, 1880.

To all whom it may concern:

Be it known that l, GEORGE H. PERKINS, of Philadelphia, Pennsylvania, have invented an Improvement in Nail-Holders for Box-Nailing and other Nailing Machines, of which the following is a specification.

My invention relates, in general, to a class of devices employed in machinery for nailing boxes or driving pegs and nails in various material. It relates more specifically to mechanisms'employed to receive, retain, and present the nail or peg in proper position to both be acted upon by the driving devices or plungers, and to be entered into the material to be united. g

Although of general applicability to pegging and nailing machines, I havein this specification described my invention as embodied in a nail-holder for box-nailing machinery. The nails intended to be employed in the form of holder represented are ordinary headed boxnails.

In the accompanying drawings, Figure 1 is a front elevation of a convenient embodiment of my device, showing the nail-holder, plunger, and plunger-carrier guide. Fig. 2 is a side sectional elevation of the same; .Fig. 3, a top sectional view of the same on the line a a of Fig. 2; Fig. 4, a top sectional plan on the line b b of Fig. 2; Fig. 5, a sectional side elevation of a convenient means of securing a plunger rigidly within its carrier; Fig. 6, a similar view of the same on the line of division of the threaded butt of the plunger.

A are cross-bars, secured to the frame-work of any nailing-machine.

B is the carrierguide, through which the plunger-carrier reciprocates, the same being a journal of any suitable construction.

0 is aolamp -plate, arranged to bear against the cross-bars A, and adapted, by meansof the bolts D, to retain the carrier-guide fixedly upon the cross-bars.

E is the plunger-carrier, being a rod made either square or provided with a feather, and so fitted within the guide B as to be prevented from rotating therein.

F is a wrist-pin, adapted to receive the connecting-rod or other device, whereby a reciprocating motion is imparted to the plunger-carrier. The guide B is slotted longitudinally (No model.)

upon its rear face, to permit of the reciprocation of the wrist-pin F.

g It is obvious that the carrier-guide B can be adjusted laterally at an angle upon the crossbars by loosening the bolts D, adjusting it to the desired inclination, and retightening the bolts, the clamp-plate securing it at the desired lateral angle upon the tightening of the latter.

G are depending brackets from either side of the carrier-guide, which pass down and sustain the nail-holder proper.

H is the plunger, secured to the lower extremity of the plunger-carrier E. The attachment of these parts may be effected in any desired manner. I have, however, devised the following means of securing the plunger in such manner that it cannot shake loose in the action of the machine-that is to say, I split the threaded butt I of the plunger entirely through, as at J, and provide a key or wedge, K, below the threaded butt and in the head of the plunger, which, after securing the butt in place, I tighten up so as to wedge apart the threaded halves of the butt, and thereby retain them rigidly within their socket in the plunger-carrier.

The brackets G unite at a point marked g, to form a depending holder-block, L, to which is secured the nail-holder M, the latter being a piece of metal Wrapped around upon itself to form a funnel-shaped device, provided with move upwardly and outwardly, to permit (in conjunction with the springs hereinafter referred to) the passage of the nail. The wings of the holder are joined together to the rear of the holder-block by a filling-up piece, m, Fig. 4, for convenience, and to better secure the holder to the block.

P is a spring hung on a stud, Q, within the block, which extends down the length of the holder and within the same, being doubled back at its lower extremity to form a toe, R, which is provided with a catch, 1', engaging with the base of the holder-block and limiting the throw of the spring.

S is a nail-feedin g tube,located in such manner as to open and discharge its nails, one by one, into the holder, and so relatively placed with regard to the plunger as not to hinder the action of the same.

Such being the construction of my invention, it is obvious that when a nail has been fed into the holder it will rest within the same and he caught between the front side and the spring. Upon the descent of the plunger it encounters thehead of the nail, and the nail is forced through between the holder and its spring, the spring being compressed and the holder moved or lifted upwardly and outwardly. Upon the return of the plunger, after the driving of any given nail, the spring and the nailholder resume their former positions, a new nail is fed, and the action is repeated.

It is obvious that my device, being made in a continuous whole-that is to say, the nail-holder proper, the plunger, plunger-can rier, and carrier-guide being all united together--is adapted to be set at any desired angle on either side of the perpendicular, whereby the nails can be driven at any desired angle, instead of being in every case driven vertically. I consider this adjustability of the de vice its most important feature, as the device is not only not limited in its adjustability to a given angle, but is adapted to many and varying angles, while,when desired,the devicecan be fastened perpendicularly, so that the nails are not driven at an angle, but driven straight.

it is also obvious thattheconstruction of the nail-holder is such as to permit the passage and accurate driving of nails of varying sizes, the adjustment of the spring and funnel being such that varying sizes are retained prior to theaction of the plunger, and subsequently permitted to be driven through with equal certainty.

The device is of very simple construction, can be manufactured cheaply, is not liable to get out of order, and is of such construction plate 0, in combination with the carrier-guide B, and with the cross-bars A, or other fixed portion ofthe frame-work, by means oftighteningup bolts D, which act to cause the clamping at the desired angle of both clamp-plate and carrier-guide upon the cross-bars, substantially as shown and described.

3. As a device for retaining and permitting the discharge of nails of varying sizes, a tubular receptacle or nail-holder, M, provided with an inclosed spring, P, and fitted with wings m, slotted at O, in combination with a holderblock, L, having a pivot, N, substantially as shown and described.

4. As a device for permitting the upward and outward movement of the nail -holder proper, the oblique slots 0 in the Wings of the nail-holder, in combination with the transverse pivot N in the holder-block.

In testimony whereof I have hereunto signed my name this 1st day of May, A. D. 1880.
